Right. My example tried to show a case where they can't be queried. The
board or the wiring causes signal degradation, which can be fixed by
increasing the bridge output voltage slightly.

So it has nothing really to do with the panel, but the board.

I fully admit that it is a purely theoretical case, and I don't have any
real use cases in mind right now.
